Physical addiction or psychological addiction – Is there a real difference?
There's no such thing as a purely psychological addiction
This is another one of the basic questions I get regarding addiction.
seems that people think about physical addiction and psychological
addiction as somehow separate processes. I think this distinction makes
no sense. Even if people really meant what they were saying, the brain is undoubtedly part of the body, and therefore, psychological addictions are also physical.
The "Physical Addiction" Vs. "Psychological Addiction" truth
What people are really referring to when they make this comparison is the distinction between physical withdrawal symptoms and the addictive process in the brain. There's no doubt that some substances, like alcohol, opiates, and the likes, leave long term users with horrible withdrawal
symptoms that are terrible to watch, and even worse to go through. In
fact, early addiction theories asserted that it was this horrible
withdrawal syndrome that made people go back to drugs. This was called the Tolerance-withdrawal addiction theory.
In one of my previous posts about marijuana addiction, a reader suggested that since marijuana does not produce horrible withdrawal symptoms, it can not be physically addictive. While withdrawal from marijuana, cocaine, methamphetamine, nicotine, and numerous other drugs does not result in the stereotypical "opiate-withdrawal-flu-like-syndrome," there is no doubt that real withdrawal from these substances exists for long term users and it sucks: Fatigue, depression, anxiety, sleep disturbances, and trouble eating are only some of the symptoms that tend to show up.
Withdrawal – The real physical addiction
Withdrawal symptoms occur because the body is attempting to counteract the stoppage of drug ingestion. Just like tolerance builds as the body adjusts to chronic drug use, withdrawal occurs as the body reacts to its cessation.
As crystal meth increases the amount of dopamine present in the brain, the body reacts by producing less dopamine
and getting rid of dopamine receptors. When a user stops putting meth
in their body, the low production of dopamine must increase and
additional receptors must be inserted. Like tolerance,
the process of withdrawal, even past the initial, obvious, symptoms, is
a long and complicated one. For crystal meth addicts, the initially low
levels of dopamine result in what is known as anhedonia,
or an almost complete lack of pleasure in anything. There's no mystery
as to why: Dopamine is one of the major "pleasure" neurotransmitters.
No dopamine, no pleasure.
The process of addiction in the brain
if we're going to try to dissect which drugs cause what effects on the
body, it's important that we understand the underlying causes for those
effects and that we use the proper language. Withdrawal, tolerance, and addiction are different, though obviously related topics.
Their interplay is key for understanding the addiction process, but
their more subtle points can often be lost on those observing addicts
unless they are well trained.
As I'd mentioned in earlier posts, our current best notions about addiction are that the process involves some obvious physical and psychological processes and some much more subtle effects on learning that
are still being studied. A study I'm currently conducting is meant to
test whether drugs interfere with some of the most basic learning
processes that are meant to limit the amount of control that rewards
have over behavior. Such fine distinctions are no doubt the result of
the ways in which drugs alter the neurochemical reactions that take
place in our brain. Such basic changes can not possibly be seen as any less important than physical withdrawal symptoms.
All in all, the only way to look at Addiction
is as both a psychological addiction AND a physical addiction that are
inextricably liked through our psyche's presence in the brain,
a physical part of the body. It may seem like a small thing, but this
distinction makes many users feel as if their problem is less, or more,
sever than that of other addicts. As far as I'm concerned, if you have
a behavior that is making your life miserable and which you can't seem
to stop, it doesn't matter if you're throwing up during withdrawal or
not. It's an issue and you need help.
